Electrolytic Refining - Mining Fundamentals

Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electro-refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode. Both the cathode and anode are dipped in an electrolytic cell containing an ...

Extraction of Gold

When the gold contains platinum and related metals, it is submitted to further refining. Part of the platinum is dissolved out by the treatment with nitric acid. Iridium was formerly slagged off by fusion with potassium nitrate, but all the platinum is simultaneously slagged, and can be recovered only by a cumbrous process.

2010-3-23  We lowered the temperature to 1100°C, but still every third smelting or so the gold is contaminated with tin. We then tried to clean it with lead and used MgO cupels, but the gold is not completely clean, it seems. It still is brittle and not good for jewelery making. Off course, we could use electrolysis and get it refined.
